Photosensitive composition, colored pattern and method for producing same

Abstract

A photosensitive composition contains a polysiloxane compound, a photoacid generator, a coloring agent and a solvent. A content of the coloring agent with respect to a total solid content of the composition is 5% by weight or more. The polysiloxane compound contains a cyclic polysiloxane structure and a cationically polymerizable functional group. The polysiloxane compound may further have an alkali-soluble functional group. A content of the polysiloxane compound with respect to the total solid content of the composition is preferably 20-80% by weight. The photosensitive composition is used, for example, in formation of a colored pattern.
